Insertion Point
This section defines the insertion points for girder placement. Each bearing requires at least one insertion point, and precast girders need insertion points at both their start and end locations.
Steps
Step 1: Navigate to Insertion Point
Navigate to Bridge Geometry > Insertion Point in the tree view.
Step 2: Create First Insertion Point
Click the three-dots icon on the first cell under Location and set it to Abut1.
Step 3: Define Insertion Points at Abut1
Since there are five girders from Abut1 to Pier1, define five insertion points at Abut1. Enter the Transverse Offset and Longitudinal Offset values for each insertion point as shown.
Step 4: Create Remaining Insertion Points
Repeat the process to create insertion points at all support locations (Pier1, Pier2, and Abut2), setting the appropriate transverse offset values for each.
Quick Tip: Skew Angle and Offset Calculations
For support lines with skew angles greater than 0, special calculations are needed:
Transverse Offset (T value): User must enter the T value for skewed supports.
Longitudinal Offset: For skewed support lines, the longitudinal offset must account for the skew angle.
Quick Tip: Transverse Offset Direction
Offset values use the Profile Grade Line (PGL) as the reference point.
Verification
After completing these steps, your insertion point layout should match the view shown below.
